If you are an AFPS 75 or AFPS 05 member who gets transferred to AFPS 15, your benefits built up to 1 April 15 will be protected. I gave someone a steer on one of the other military sites this morning which might clarify things for you.
The chap in question was on AFPS 75 and would be leaving at the 22 yr point in Dec 15. He would get:
An immediate pension of 96% of the AFPS 75 22 yr rate for his rank and a tax free lump sum of three times that amount
PLUS
A preserved AFPS 15 pension worth 1/47th of his pensionable pay for the balance of his service. This is payable at his State Pension Age.
An EDP lump sum worth 2.25 times the preserved pension
An EDP income stream worth at least 34% of the preserved pension
The point others were making was about the 18 yr old who joins for a 20 yr period. He would be too young to get an EDP as he would only be 38 when he left. He would leave with a preserved pension payable at State Pension Age
